Data use and technology

What data visualization can show us?

Data visualization tools provide a simplified approach to creating visual representations of extensive data sets. They bring together complex and extensive data collections and translate them into more manageable representations. Data visualization allows researchers to delve deeply into a multitude of variables that can impact an environment. It is especially important in the case of Kalmar Dam to demonstrate the multidimensional task of making the lake cleaner.

Internet of things (IoT) and the Helium Network

Kalmar Dam's monitoring and communication system counted with the technology of the Internet of Things (IoT) and the Helium network. These technologies enhance the dam's efficiency and contribute to its sustainable mission.

IoT and Its Role

The Internet of Things (IoT) represents a groundbreaking technological innovation that facilitates the integration of devices into various objects, ranging from vehicles and electronic systems to rooftops and lighting fixtures. These devices are equipped with the ability to measure environmental conditions, generate valuable data, and seamlessly communicate this information over a network. It includes a distance sensor, wireless micro-weather station, and wireless wind station

Helium Network: A Connectivity Breakthrough

Kalmar Dam stands as an exemplary model of innovation, sustainability, and the harmonious coexistence of recreational activities and nature. The efforts at Kalmar Dam contribute to making the Baltic region cleaner and healthier.

Violin plots

Range of values

A violin plot is a statistical graphic for comparing probability distributions. It is similar to a box plot, with the addition of a rotated kernel density plot on each side

violin plots are used to represent comparison of a variable distribution (or sample distribution) across different "categories". For example, here we apply violin plots to three variable,Water depth, Electric conductivity and temperature.

In this way, for the three variables, we can see both the diversity of values and their probability

Violin plot for the values of Temperature.
